I agree that the whole article seems slimy.
Having said that - for a short time in a young woman's life she is highly desired by men of all age groups. How can you take 50 year age range of of men who think they can (and should) get 5 year age range of women?
But if a woman survives this 5 year period then relationships with men can be balanced and satisfying. Men still want women and women still want men, but it seems to be balanced.
